Hi,
For the university I'm analyzing a old android malware and they gave me two samples. The apks are the same (code, dex, res etc...) except for additional files .SF and .RSA in the META-INF folder. In the .SF files, it is possible to see that the digests are calculated for not existing files in the apk. For this reason (I think) the apk cannot be installed through adb in the virtual machine because the signature check fails. Is there a way to exploit this files in a malicious way? I have only noticed that less antimalwares mark this apk as a malware, probably because the hash is different.
Thank you in advance.

By default, the debug APK is created in app/build/outputs/debug/app-debug.apk & release APK is created in app/release/app-release.apk.
Is it possible to change the debug APK location to app/debug & instead of app-debug & app-release is it possible to assign the default name to something like {app name}_{version}_{timestamp}_{debug/release} without manually renaming? Also, a debug APK is created when we directly run from Android studio which is not installable & would like to exclude this particular APK.

Hello,
I was able to get an update .zip file, I want to edit the update and add some system apps.
I was trying to unpack the system.new.dat but I didn't have any luck, I tried dat2img and several more tools.
How can I do this process?
The update.zip is attached
Thanks

Sorry for my ignorance, I'm a beginner.
I have a system.ext4 file that I was able to extract from my firmware. I need to delete the unwanted APK files.
I used 7-Zip to view the files inside the .ext4, but I can't delete the apk files as it says it's "read only".
What software can I edit the .ext4 file so that I can have free access, or at least delete files within it?
Thanks.

Pulling my hair out!
I purchased the tablet so that I could use it on my upcoming caravan travels. I put together a number of itineraries using HTML and Javascript.
When I got the tablet, I copied my suite of files to the tablet from my laptop. Yes, my ‘system’ was working perfectly on the laptop and I had already tested them successfully on an old Samsung Tab 4.
No problem with the files – they ran as expected.
Then, not having a lot of experience with tablets, I allowed an update to go ahead. Ever since then, my files do not run properly!
Problem Summary
1 Files are there but my Lenovo cannot see them.
2 Cannot create a shortcut to the home screen.
3 Different app allows me to see my files.
4 HTML file does not function properly – it’s like it can’t see the other folders it references.
5 Links do not work – “No application can open this link”
Does anyone have any idea what could be wrong? I tried rescue flash, but that failed more than once!
